Lmao, c'mon guy. the link you posted has nothing to do with s-off for one thing, simply links to the Viper 1s thread and for another thing nobody has lost s off. Looks like some reading is in order on your part
No matter how well it worked in the past: do NOT go about S-OFF'ing or Brick Downgrading your phone from a virtual machine. This simply is because the connections made in QDL mode are highly unstable and cannot be maintained well. It needs a very secure and proper cable connection with very reliable driver settings. This mainly applies to the Brick Downgrade which is using QDL Mode but not so much to S-OFF. However, the chances to mess something up from a VM are much higher simply because the connections have to run out of the VM into the physical layer and that always includes tricky code that can bug you. Without FULLY understanding how the connections are made and maintained, i would not even attempt to make it working. MUCH safer to go looking for a physical Win Machine you can use.
Sorry for the OT but i haven't seen you on our Beta Chat since like freaking ages.... Hope you're well though buddy.

If you have some very good picture with loads of colors and edges and blurs, like some standardazid reference picture, you can see the BRAVIA impact on that picture before and after enabling BRAVIA. It is nothing u can actually actively "use". It is just making picture and video display on the phone screen better.
And regarding XLOUD: same for sound. Its just intended to increase volume and better up sound quality, however, that one i find quite useless, as most sound mods. If it was my ROM, i had not included it.
The Devs chose to not listen to my ranting in the Beta Chat though

That just means you haven't found all bugs yet 
Some things most definitely do NOT work, like the Backlight brightness tweaks for instance.
[EDIT]
The two Devs tricked me while i was working all week, just figured tweaks changed again since i updated the DOC. Release has different tweaks than Beta.
Oh well... some job to do before i can continue trolling you here
